First I'd go with the heatsink, that will prolong your motor life. Then the higher capacity battery packs as they are cheaper than the stock ones, and perform better too, that will allow you to run more often as you will have more packs to fly with. Then I'd get the cellpro 4s charger so I could charge my packs in 50min or less verus the 2 hours the stock charger takes, and I'd keep the stock charger to charge a third pack if needed. Then the rest will give you better performance, which you will want once you can outfly it! Enjoy!
